Tom Nelson and his Nelson Racing Engines outfit are known for building crazy powerful engines that have their appearance dialed up to 10. You most commonly seem them in street cars, but Oakland, California’s Matth

When NRE put this 260-inch turbo LS on the dyno and held it at WOT for five minutes, it was impressive.

When they then ran it at WOT for an hour, it was mind-blowing.

Records are made to be broken and no one knows that better than SSC.

The company just reclaimed the record for the world's fastest production car.

Tom Nelson built a street engine with big cubes, big turbos, and an interesting dual-fuel system to make big power.

Even with mild boost numbers, the engine makes well into the four-digit-horsepower range.

After running the five-minute WOT dyno test eleven more times with zero failures, it's time to inspect the engine.

Tom Nelson not only opens the engine, but opens up about some of the secrets in the build.

A 1,200 horsepower LS displacing only 260 cubes is impressive in and of itself.

Add in the requirement to withstand a five-minute WOT dyno pull, and we're talking next level performance.

What happens when you take a LSX 454 crate engine and completely rebuild it into an off-road trophy truck engine?

Nelson Racing Engines shows us what goes into such a project.
